When packaging any item, no matter what kind of material or container is used for packaging, there is finally a problem of sealing or tying the package. The materials used to seal packaging containers are called packaging and packaging materials, and various materials for packaging products and combination packages are called packaging and binding materials.
The purpose of sealing and strapping in inner packaging, outer packaging, large packaging and small packaging is not completely the same, but their functions are nothing more than the following aspects: 1. Prevent the contents from coming out, leaking, and dissipating; 2. Preventing the oxidation of products , Corrosion, etc., to extend product life to increase product value; 3, to prevent the internal product is contaminated, stolen or removed stolen; 4, to strengthen the strength of packaging containers, and sometimes beautify the role of goods; 5, to facilitate storage and handling.
The tying materials in the package mainly include plastic tying tapes and plastic ropes, and are mainly used for corrugated cartons and other bulk foods and vegetable tying. Its role is to bundle the packaged goods together, compress the volume, increase the strength of the package, and facilitate loading and unloading. There are also seals, anti-theft, and the role of preventing the loss or scattering of the package.
The plastic strapping tape for packaging is made of polyethylene and polypropylene resin as the main raw materials, and nylon and polyester are also used as the raw materials, which are obtained through uniaxial extrusion. The elasticity of the plastic banding belt is good, the strength is high, the water resistance is good, the chemical resistance is strong, the quality is light and soft, and it can not only be bundled but also be bundled by machines. Easy to use, low cost, can be made of red, white, blue, yellow, green, and other colors, according to the color bundle of different grades of goods, to facilitate the classification of goods, improve delivery efficiency. In addition to the sealing and strapping of corrugated boxes, it is also possible to tie materials, fruits, etc. The tensile strength of polyester and nylon straps is good, while the cost of polyethylene and polypropylene straps is low, and the resilience of polypropylene is good. Binder straps of different materials can be used as required.
The plastic straps are classified into two types according to the use method: machine belts and manual belts. The model name of the strapping is the material, the nominal size and the type of the width and the thickness are distinguished: The strapping belt is widely used in food, pharmacy, household appliances, and daily chemicals. , light industry, electronics and many other industries.
Today, with a very active market economy, any enterprise can not do without packaging. In recent years, with the continuous demand for the production of large, medium and small enterprises, the demand for packaging has grown rapidly. As a supporting material, the packaging belt is in all areas of national economic development. There is a wide range of development prospects. The total demand for the packaging machinery market is about 5 billion yuan. Therefore, the packaging industry will be produced with a huge market prospect.
